Low Calcium Symptoms

[austin93]

What are some problems associated with low calcium? Mine has been around 330 to 340 for the past month. Would a very slow stn be a symptom?

Low calcium shouldn't cause STN. The cause is really not known. Still raising calcium is a good idea. Low calcium will cause slow coral growth and slow coralline growth.

STN isn't very well understood, but I agree that slowing stony coral and coralline growth would be the primary symptoms.
